Well, the evidence is that we are continually evolving, those who claim otherwise seem to wear blinkers. Anyways, I think we will eventually lose wisdom teeth altogether.

Anthropologists believe wisdom teeth, or the third set of molars, were the evolutionary answer to our ancestor’s early diet of coarse, rough food – like leaves, roots, nuts and meats – which required more chewing power and resulted in excessive wear of the teeth. The modern diet with its softer foods, along with marvels of modern technologies such as forks, spoons and knives, has made the need for wisdom teeth nonexistent. As a result, evolutionary biologists now classify wisdom teeth as vestigial organs, or body parts that have become functionless due to evolution.edit on 22-2-2013 by Qumulys because: (no reason given)edit on 22-2-2013 by Qumulys because: (no reason given)

Well...here's the hole in that logic. You are assigning a value to an unknown. This being assigning Adam and Eve to a specific ancestor of Man and you are doing so based upon opinion. This goes against the tenements of logical deduction as well as allowing an unknown a value. It is the same as a+b=10...then just declaring b is 4...it cannot be proven to be so.

Again...hole in your logic...our Mapped Genome shows us every direct ancestor from the beginning of Life on Earth...all the way back to the first Single Celled Organism.
We KNOW conclusively what were and were NOT our ancestors.
